I've got an Xcal2 w/ custom tunes and 3.73's. and its just fine . I like the top end it has 115+ mph .I don't take it offroad though. If , I did there would be lower gears in the future .
lol not to rain on your parade but the f150 is the slowest 1/2 ton truck and an edge and cai still probably won't make it any faster than the other trucks.
